Congratulations on your purchase of a
Yamaha snowmobile. This model is the result
of Yamaha’s vast experience in the production of fine sporting and touring snowmobiles.
It represents the high degree of craftsmanship
and reliability that have made Yamaha a leader in these fields.
This manual will give you an understanding of
the operation, inspection, and basic maintenance of this snowmobile. If you have any
questions concerning the operation or maintenance of your snowmobile, please consult a
Yamaha dealer.
To maintain the high quality and performance
of this snowmobile, it is important that you and
your Yamaha dealer pay close attention to the
recommended maintenance schedules and
operating instructions contained within this
manual.
PLEASE READ AND UNDERSTAND THIS
MANUAL COMPLETELY BEFORE OPERATING THE SNOWMOBILE.
NOTE:
● Yamaha continually seeks advancements
in product design and quality. Therefore,
while this manual contains the most current
product information available at the time of
printing, there may be minor discrepancies
between your snowmobile and this manual.
If there is any question concerning this
manual, please consult a Yamaha dealer.
● This manual should be considered a per-
manent part of this snowmobile and should
remain with the snowmobile when resold.
EWS00020
WARNING
Failure to follow WARNING instructions
could result in severe injury or death
to the
snowmobile operator, a bystander, or a
person inspecting or repairing the snowmobile.
ECS00010
CAUTION:
A CAUTION indicates special precautions
that must be taken to avoid damage to the
snowmobile.
NOTE:
A NOTE provides key information to make
procedures easier or clearer.
Particularly important information is distinguished in this manual by the following notations.
The Safety Alert Symbol means ATTENTION! BECOME ALERT! YOUR SAFETY IS
INVOLVED!
When you ride your snowmobile, you must
know and use the following for your safety.
Severe injury or death may result if you ignore
any of the following.
Before operating
1. Read the Owner’s Manual and all labels
before operating this snowmobile. Become familiar with all of the operating
controls and their function. Consult a
Yamaha dealer about any control or function you do not understand.
2. This snowmobile was not manufactured
for use on public streets, roads, or highways. Such use is prohibited by law, and
you could collide with another vehicle.
3. This snowmobile is designed to carry the
OPERATOR ONLY.
Passengers are prohibited. Carrying a
passenger can cause loss of control.
4. Do not operate the snowmobile after
drinking alcohol or taking drugs. Your
ability to operate the snowmobile is reduced by the influence of alcohol or
drugs.
5. For safety and proper care of the snowmobile, always perform the pre-operation
checks on page 29 before starting the engine. Check the throttle, brake, and steering for proper operation every time before
starting the engine. Make sure that the
throttle lever moves freely and it returns
to the home position when it is released.
6. Apply the parking brake before starting
the engine. Never drive the snowmobile
with the parking brake applied. This may
overheat the brake disc and reduce braking ability.
7. Do not allow anyone to stand behind the
snowmobile when starting, inspecting, or
adjusting the snowmobile. A broken
track, track fittings, or debris thrown by
the track could be dangerous to the operator or bystanders.
8. Handle fuel with care; it is HIGHLY
FLAMMABLE.
● Never add fuel when the engine is run-
ning or hot. Allow the engine to cool for
several minutes after running.
● Use an approved fuel container.
1
Safety information
● Fill the fuel tank outdoors with extreme
care. Never remove the fuel cap indoors. Never fill the fuel tank indoors.
● Never refuel while smoking or in the vi-
cinity of an open flame.
● Make sure that the fuel tank cap is
closed securely after refueling. Wipe
up any spilled fuel immediately.
9. If you swallow some gasoline, inhale a lot
of gasoline vapor, or get some gasoline
into your eyes, see your doctor immediately. If any gasoline spills on your skin or
clothing, immediately wash your skin with
soap and water, and change your
clothes.
10. Wear protective clothing. Wear an approved helmet, and a face shield or goggles. Also, wear a good quality
snowmobile suit, boots, and a pair of
gloves or mittens that will permit use of
your thumbs and fingers for operation of
the controls.
Operation
1. Do not run the engine indoors, except
when starting the engine to transport the
snowmobile in or out of the building.
Open the outside doors; exhaust fumes
are dangerous.
2. Be careful where you ride. There may be
obstacles hidden beneath the snow. Stay
on established trails to minimize your exposure to hazards. Ride slowly and cautiously when you ride off of established
trails. Hitting a rock or stump, or running
into wires could cause an accident and
injury.
3. This snowmobile is not designed for use
on surfaces other than snow or ice. Use
on dirt, sand, grass, rocks, or bare pavement may cause loss of control and may
damage the snowmobile.
4. Avoid operating on glare ice, or on snow
which has a lot of dirt or sand mixed in.
Operation under such conditions will
damage or result in rapid wear of ski runners, drive track, slide runners, and drive
sprockets.
5. Always ride with other snowmobilers
when going on a ride. You may need help
if you run out of fuel, have an accident, or
damage your snowmobile.
6. Many surfaces such as ice and hardpacked snow require much longer stopping distances. Be alert, plan ahead and
2
begin decelerating early. The best braking method on most surfaces is to release
the throttle and apply the brake gently—
not suddenly.
Maintenance and storage
1. Do not leave the snowmobile on its left
side for an extended period of time. Fuel
may leak out from the fuel breather hose.
2. Modifications made to the snowmobile
not approved by Yamaha, or the removal
of original equipment may render your
snowmobile unsafe for use that may
cause severe personal injury. Modifications may also make the snowmobile illegal to use.
3. Never store the snowmobile with fuel in
the fuel tank inside a building where ignition sources are present such as hot water and space heaters, an open flame,
sparks, clothes dryers, and the like. Allow
the engine to cool off before storing the
snowmobile in an enclosed space.
4. Always refer to the “STORAGE” section
on page 75 if the snowmobile is to be
stored for an extended period.
5. Maintain or replace safety and instruction
labels, as necessary.

Engine overheating prevention
system
This model is equipped with a system, which
prevents overheating when the engine is
idling.
When the engine has been idling for 3 minutes or longer and the coolant temperature
has risen above 100 °C (212 °F), the engine
automatically stops to prevent overheating.
NOTE:
The headlights, meter lighting, and taillights
come on after the engine is started.

(T.O.R.S.)
EWS00040
WARNING
● If the T.O.R.S. is activated, make sure
that the cause of the malfunction has
been corrected and that the engine can
be operated without a problem before
restarting the engine.
Control functions
● Be sure to use the specified spark plug
and spark plug cap. Otherwise, the
T.O.R.S. will not work properly.
If the throttle bodies or throttle cable malfunctions during operation, the T.O.R.S. will operate when the throttle lever is released.
The T.O.R.S. is designed to override the fuel
injection and limit the engine speed to less
than the clutch engagement speed if the throttle valves fail to return to the idle position
when the throttle lever is released. (See page
